CONTROLLING MECHANISM FOR AUTOMATIC MACHINES.

Application filed August 20, 1968. Serial N 449,409.

To all whom it may concern Be it known that I, ERASTUS E. VVINKLEY,citizen of the United States, residing at Lynn, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Controlling Mechanism for Automatic Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to a controlling mechanism for automatic machinesor apparatus which is well adapted for use in automatically maintainingthe proper angular relation between the workand tool, or between thework and feed mechanism, of machines in which the tool operatesprogressively along the work,.the term tool be ing used to designate anyinstrument or combination of instruinentalities for operating on thework. Machines of this character are extensively used in the manufac-.ture of boots and shoes for performing various operations upon theshoesoles or other parts connected or to be connected therewith, and itis one object of the invention to provide a novel and improved mechanismfor automatically correcting the angular relation of the work and tool1n such machines so that the tool automatically maintained in properangular relation to the surface of the work, or to the line of feed, asits point of operation progresses along the work. j

Many of the machines of the character above indicated are provided withfeeding means constructed to cause a relative movement of the tool andwork in the general direction of the periphery of a shoe sole, and theprescribed travel of the tool along the work'is secured by relativelyswinging the tool and work to correct their angular relationinaccordance with the curvature of the sole the relative swingingmovements being usually effected by the operator, who swings the work asthe feed progressesto maintain the edge of the sole or some marginalchannel or abutment thereon in engagement with a suitable gage. In thesemachines theperiphery of a sole, or the marginal abutment with which thegage contacts during the action of the feeding means, constitutes a formfor determining the path of travelof the tool along the work.

It is a further object of the invention to provide novel and, improvedmechanism for controlling the corrective swinging movements in suchmachines by the contour of the form.

One feature of the invention accordingly contemplates the provision in amachine provided with feeding means for effecting a relative travel of atool along the work .in thedirection of the periphery of a form, ofmechanism controlled by the contour of the form for relatively swingingthe feeding means and work in either direction to cause the path oftravel ofthe tool along the work to correspond to the contour of theform. Broadly considered, the form may be the periphery of the articleto be operated upon, as for instance in a machine for operating upon themarginal portion of a sole blank,

or the form may be a pattern separate and distinct from the work. Therelative feedingmovement of the feeding means and the form and work, andthe relative swinging movements, maybe caused by movement of either thefeeding means or-of the form and work.

In the machine whose operation the invention is more particularlydesigned to im-,

prove and render automatic, the feeding means is constructed to impartmovement to I i usually employed'in machines for doing the same work andto provide means for automatically swinging the work and form inaccordance with the contour of the form.

The broader features of the invention contemplate the provision of anysuitable mechanism for controlling the relative swinging or angularmovements of the work and feeding means, orof the work and tool, by thecontour of the form. It is preferred, however, to employ for thispurpose a mechanism embodying certain further features of invention. Inaccordance with one of these features, the relative swing or otherangular movements are controlled by a feeler arranged to engage theform, and by its position determine the corrective movement requisitefor causing the path of travel of the tool valong the work to conform tothe outline of the form, or for maintaining the tool in proper angularvrelation tothe work.

be readily understood from an inspection of the accompanying drawings,in which- Figure l is a side elevation of a machine for channelingoutsoles of boots and shoes embodying the invention in itspreferredform;

Fig. 2 is a plan view of the machine; Fig. 3v

is afront elevation; Fig. l is a transverse sectional elevation; andFlg. 5 1s a detail showing a part of the controlling mechamsm.

In the drawings the invention is shown embodied in a machine foroperating upon the marginal portion of a shoe sole, the particularoperation which the machine is de-' signed to perform being the cuttingof a channelin the surface ofthe sole at a definite distance from itsedge or periphery.

I The machine is provided with a channeling knife 1, a gage 2, and.feedwheels 3 and 4,

these parts beingconstructed and arranged isusual in machines forcutting the channel in outscles. for boots and shoes. In order that thefeed wheelsmay effectively grip and feed the work, and may be readilysep-v arated for the removal and introduction of the shoe sole, theshaft 5 to which the upper feed wheel is secured is mounted in a veratically movable bearing 6 and is held in normal position by a spring 7.The feed wheels may be separated by a cam8 arranged to engage apin 9projecting from the bearing 6, and the cam is provided with anoperatinghandle 10 arranged within convenient reach of the operator. The wheelcarrying shaft 5 is connected by a universal joint'll with a shaft 12,which is connected through gearing 13 with the shaft 14; which carriesthe lower feed wheels. wheels are continuously driven during theoperation of the machine through a shaft 15 which is connected bybeveled gears 16 with the shaft 14:, and is provided at its lower endwith a worm wheel 17 engaging a worm-l8 :secured to the driving shaft19. The driving shaft is provided with a clutch member 20 arranged 'toengage a clutch member formed on the driving pulley 21, and a lever 22is provided for throwing the driving clutch into and out of action.

In operating machines of the type illustrated in which the path oftravelof the tool The feed,

of a shoe sole, it. is customary for the operator to swing the work asit is advanced by along the work corresponds to the" contour the feedwheelsv or other feeding devices so that the edge of the sole iscontinuously in erating tool. In accordance with the present invention,the swinging of the work as it is advanced by the feeding devices, sothat the pathv of travel of the operating tool along the work willcorrespond to the contour of the sole, is automatically effected, andthe attention of the operator during the operation of the machine uponthe work is not required. Y

, In the construction shown, the: sole Ato be operated upon is supportedin a carrier. comprising two clamping plates 23 and 24 between which thesoleis held. In order that the sole may move freely in any. direc- Ition in the plane of operation, the carrier is mounted in the free endof a frame 25, the

other endoffwhich is pivotally supported upon a vertical shaft 26 whichis mounted in the end. of a second frame 27, the other v end of which ispivotally supported upon a vertical shaft 28 mounted in fixed bearingsin thefra-me of the machine. In order that the carrier may be swungabout an axis at right angles to the operating plane as it 1s moved inthe operatingplane by the feeding devices, the carrier is pivotallysupported to.

turn about a vertical axis in the frame 25. The pivotal support for thecarrier in the end of the frame 25 consists of a shaft29. carrying thelower clamping plate 23, and

a sectional shaft 30 to which the upper clamping plate .24 is connected.The two sections of'the shaft 30 are connected by a coupling 31 whichallows a vertical move ment of the clamping plate 24'. The clamp-' ingplate is forced yieldingly toward the i clamping plate 23 by asp-ring 32interposed between the two sections of the shaft 30. The clamping plate24 may beireadily raised to allow the removal or insertion of a sole;

blank between the clamping platesby press- 'ing'together the twohandles33 and 3a which project '1 respectively from ,the bearing inwhich the upper sectionof the shaft 30 is mounted, and from the hub35-by which the.

clamping plate at is secured to thelower section of the shaft. I

The swing ng movements of the work carrier requisite for securing theproper pre-,

sentation of the work to the tool as'it is'ad vanced by the feedingdevices are efiected by turning the shafts 29 and 30, whichare arrangedin axial alinement with each other. The connections through wh1ch theturning movements are effected are as follows. 'Radially projecting arms36 and 3'1 are secured tothe ends of the shafts 29 and 30, and thesearms are connected by means of links 38 70 contact withfthe gage, inorder that the jwork may be properly presented to' the opwith arms 39secured to the opposite'ends of the vertical shaft'26. The arms 39 arealso connected by links 40 with arms 41 secured to the opposite ends ofthe vertical shaft 28. The arms 36 and 37 at the opposite ends of thepivotal support for the carrier are arranged at an angle of 90 with eachother, and the arms at the opposite ends of the shafts 26 and 28 aresimilarly arranged to avoid dead centers in the connections throughwhich motion is transmitted from the shaft 28 to the work carrier. Theseconnections not only act as meansfor transmitting swinging movements tothe carrier, but also act as means forretaining the carr1er ,and work ina constant angular position as it is moved bodily inthe operating plane,so that the movements imparted to the work and carrier by. the feedingdevices do not change the angular position of the work, or of the work.

The swinging movements imparted to the work carrier and work arecontrolled by the curvature of the sole blank,.the periphery of whichconstitutes a form or pattern for determining the path of movement ofthe tool along the surface of the sole. In the construction shown, thecontrolling mechanism comprises a feeler finger 42 arranged toengage-the edge of the sole in advance of the pointof operationof'theknife, and operating to control the action of a mechanism whichimparts rotary movements to the shaft 28 and from it through theconnections described to the shafts 29 and 30, on which.

the carrier which carries the work and con trolling form is mounted. Theposition of the feeler finger will depend upon the curvature of the edgeof the sole between the point where it engages the gage 2 and the pointwhere it engages the controller finger. The mechanism which iscontrolled by the feeler finger is so constructed and actuated that itwill operate to swing the sole about the point of operation of the knifeduring the advance of the sole through a distance substantially equal tothe distance between the point of engagement of the feeler finger andthe point of operation. of the knife, the

swinging movement being that which is required to keep the peripheryof-the sole in contact with the gage as the sole advances.

The mechanism for actuating the shaft 28 to impart swinging movements tothe sole comprises an intermittently operating actuating mechanism, theoperation and extent of movement of which depends upon the position ofthe feeler finger when in engagementwith the periphery of the sole. Theactuating mechanism shown comprises two ratchet wheels 43 and 44 securedto a shaft 45 which is connected through gearing 46 with avertical shaft47, the upperendfof which car- ;ries a gear48 engaging a pinion securedI produce a swinging movement.

to the shaft 28. The'teeth of the ratchet wheel are oppositely arranged,and are engaged at intervals by two oppositely arranged pawls 50 and 51which are pivotally mounted upon a pawl carrying block 52. The pawlcarrying block 52 is mounted in a radially extending slot formed in thepawl carrying arm 53 which is mounted to turn freely about the shaft 45.The pawl carrying arm is held yieldingly in mid-position by means. of aspring pressed yoke 54, the arms of which engage arms 55 which extend inopposite directions from the hub of the pawl carrying arm. The pawlcarrying block 52 is connected with a plate 56, the upper end of whichis provided with two laterally extending arms 57 between which the upperends of the pawls lie. A pin 58 projects from the plate 56 between theend of the pawls, and the pawlsare held in engagement with this pin bysprings 59. The plate 56 is moved vertically at proper intervals toengage the pawls with and disengage them from the ratchet wheels,through a bell crank lever 60, one end ofwhich is connectedwith theplate 56 by a link 61, and

the shaft 45will be rotated in ,a direction corresponding to thedirection in which the pawl carrying arm is moved, and this move-. mentwillbe transmitted through the connections describedto theworkx carrier,and

will cause a swinging of the work about the point of operation of thecutter corresponding to the movement imparted to the pawl v carryingarm.

The'direction and extent of movement imparted to the pawl carrying armis determined bvthe position of the feeler finger 42 through thefollowing mechanism. The rear end of the finger 42 is pivotallyconnected to the upper end of a lever 63 pivoted ona stud 64 andcarrying a roll 65 on its lower end. The feeler finger is heldyieldingly in engagement with the periphcry of the sole by a spring 66(Fig. 2) which is interposed between a fixed lug on the frame and acollar 67 formed on a rod 68,

- the front end of which is pivotally' connected to the lower arm of thelever 63. The rear end of the rod is supported in a bearing 69, and isarranged to be engaged by the upper end of a lever 70, the lower arm ofwhich is provided with a roll en-- gaging a, cam groove formed in thedisk 71 which issecured to the shaft 19. The arm 70 is operated to forceforward the rod 68 and thus withdraw the feeler finger 42 after thefeeler finger has acted to locate devices which determine the directionand extent of movementof the pawl carrying connected to a block 76mounted in guid-' a of thesu rfa'ces will engage the roll, in caseit'occupies a position to either side of its mid-position, andbytheengagement of one 80" arm 50, and, to hold the finger in retractedposition while the actuating mechanism o crates to effect the swingingof the work.

After'the swinging movement, has been coni- The roll at the end of thelower-arm of the lever 63 is arranged to coiipe'rate-with two oppositelyinclined surfaces 72 formed on theend of an actuator lever 3. The'l'everis pivoted at 74 to a disk 75' which is mounted to turn freely upon theshaft 45,.

and the rear end of the lever is pivotally ing slot formed in one arm ofa lever 77. The other armof the lever 77 carries a roll engaging a camgroove formed in a disk 78 which is'secured'to' the shaft 19. Throughsurfaces 72down0n opposite sides of the roll 65. Asthe surfaces72 passdown on opposite sides of theroll 65, one or the other or'the other ofthese'surfaces with the roll, the lever 73 will be moved either forwardor back, as the case may be. This move: ment of the lever will cause thedisk 75 to be turned in one direction or the other, ac-

cording to the position of the roll 65.' This movement ofthe disk 7 5operates to position a device which determines the movements impartedto'thepawl carrying arm 58. 7 Immediately after" this device has beenposi tioned, it is firmly held in this position by clampingthe disk 75.The lever78. may

then be raised so that the feeler finger 42' is free to be retractedand. thereafte'rito reengage the periphery of the sole. The

when the actuator lever 73 is operated to en ga'ge the roll 65 byapivoted spreader block 80 which is mounted between the upper ends of thebrake shoes. The brake shoes are forced toward each other to clamp thedisk 75 by means ofaspring 81 interposed between one of the brake shoesand nuts 82 carried on the'end of a bolt which passes through the brakeshoes.

Thespreader block 80 is operated at proper intervals to disengage thebrake.

While I have shown the invention embodied in'a machine inwhich-theperiphery i of the blank being operated upon constitutesv theform or pattern for determining the path of travel of the tool along thew'ork,

it will be understood that the invention is not confinedin itsap'plicati011 to a machine of this type, and that a separate pattern orform may be employed for determining the path of travel of the toolalong the'work,

without departing from the broader features of the invention.
